My invention may be applied to'any usual; axle, and for convenience "of illustration I 'have shown, in Fig. 1-, a usual axle a, such as'is con1m0nly found in"the better class of light 'I'ially on itsupperiside, as indicated at a ,to

receive an oil-tube-aq. The grooveiaf'ha a special shape,'.-beingoutwardlyflared at its up fer edges; as indicated at'a Figs. 2'and 3,

,for the smaller-sized vehicles being laterally flared atboth e'dgesiah and a asindicated in Fi"s.4 and-5, and thoseaused' for 'thelarger .ve oles being-flared at one side 0111 as indicatedin Figs-6 and], vWitln'nt e tube I provide allon'g strip 'a'" of' pressed, 'felt, as

.indicated-in-Fig. 10, constitutin an oil; con;

taining and deli-verin :member or applying. oil to-the moving su ace above it, this strip having a length corresponding to the 'oil-re-' ceivi'ng chamber ofthetube. -The purposeof they fiarin give a larger oiling-surface, while also -per initting the felt to loosen up and enlarge. at.

its upper surface,- asindicated in Figs. 5 and .7, the flaring edges of the tube presenting an thev tubes a arealso flared, those used .9 I is topermit theoil tofiow freely throug out the length of the tube-and.

shoulders or supporting-surfaces for holding up the felt and reve'nting' its matting down e rssed within the tube.

the tube give strength to the latter, sothat J the tube ,is not likely to become bent or broken. At its outerend the tube is filled I with lead or other suitablefclosing substance; I

as indicated at a], and isvertically'perforated or provided-With a' convenient notch or hole a for receiving a-hook a), (see Fig. 1,) wherebythe tube may be instantly withdrawn when the retaining-capKnot shown) is unscrewed from the. threads a, of the axle. Usually the tubes are sent to the'trade'with the closed end a left uncut, as-shovvn'in Fig,

- loads, there is great trouble in this class of device, because of the accumulations of sand in the oiling-tube, and consequently the oil and felt or cotton become ritty. For obviating this trouble Ileave t e rear wall a of the tube straight, so that the rear flaring edge of the axle-groove (see a, Fig. 11, and a, .Fig. 12,) cooperates therewith in forming a sand-box for catching and retaining all the sand as the wheel moves forward and preventing said sand from reaching the felt a" and interior ofthe oil-tube.

Figs. 11 and 12 show the opposite outer ends I of an axle on which the wheels rotate in the direction of the arrows when the vehicle is moving forward. In practice I have found that. this materially increases the efficiency of the device and is a great convenience as well, as it is readily cleaned and tends to maintain the wheel, axle, and tube in proper condition for a longp'eriod of time.

In use all that is necessary to do is simply to remove" the retaining-nut from the axle and theninsert the hook a, and quicklyslide out the oil-tube and 'felt. Thereupon the oil-tube is filled-with' oil, either by pouring theoil' along the edges of the felt throughout the length of the tube, or, if desired, the'felt is simply lifted out from the oil-cavity of the tube, and when the latter has been properly filled the felt is reinserted in the tube and permitted to absorb the-oil. The tube and its contained felt are then simply shoved back into place,.the nut is screwed in proper position, and all is in readiness for continued service of many weeks before further attention is needed.

I am aware that many changes in form and arrangement of parts may be resorted -to without departing from the spirit and scope I of my invention, and I wish it also understood that certain features of my invention may be used with advantage with old constructions, although I prefer to employ the entire construction as shown, and accordingly in some of my claims I have set forth the entire construction, while other claims are limited in only certain details. Having described my invention, what I claimas new, and desire to secure by Letters Patent of the United States, is

1. In anaxle-oiler, an axle having a longitudinal groove in its upper surface, combined with a removable oil containing and delivering member, said. groove being U-shapcd with deep parallel sides, whose cxtrcmp up; per portions are flared divergcntly upward, the depth of said groove being sullicicnt to maintain upright said removable oil containing and delivering member and said flaring portion acting to support the top of the latter and aiiord an extended oi ling-surface.

An axlo-oiler, comprising a rcnmvable oil tube flaring divergently upward at its top opening, and a removable oil-delivering strip occupying said tube and adapted to spread out into supported position against the flaring sides of said tube for delivering oil to the axle.

3. A11 axle-oilcr, colnprisil'ig an eil-tubc containing absorbent material for delivering oil therefrom, and an axle grooved at itsnpper side to receive said tube, said tube having a vertical rear side and said groove having a flaring rear wall, cooperating with said verti-' cal rear side of said tube to form a sand-re ceiving cavity at the rear side of said tube, for catching the sand and grit as the wheel turns forward, thereby preventing the same from entering said tube.

4. An axle-oiler, comprising a tube havin its forward longitudinal side outwardly flare and its rear longitudinal side plane, and an axle having a groove in its upper side outwardly flared at both longitudinal-edges for sustaining said flared forward side of the tube and for providing a Sandbox immediately behind said plane side of the tube.

5 In an axle-oiler, a tube having a longi- 'tudinal oil-receiving cavity open throughout its length on its upper side and a shouldered closure at its outer end and upper side, the top surface of the extreme end of said closure being smooth, and said end containing a vertical hoolcreceiving' hole for instant with-' drawal of said tube.

6.- An oil-tube for an axle-oilcr, closed excepting on its upper side, the outer end thereof being closed with 'readily-cut material such as lead and containing a vertical hole, whereby said end may readily be cut to lit an axle without interfering with the withdrawing means.

7. A vehicle-axle having at its opposite ends longitudinal grooves in its upper side, oil-tubes contained therein for endwise removal, each tube having a vertical rear side, whose top edge extends approximately flush with the circumference of the axle and said axle having a longitudinal cavity at the rear side of each of said tubes, formed by said groove and the vertical side of the adjacent tul e for collecting-sand.

8. In an axle-oiler, a removable oil-tube, and a strip of absorbent material for dis tributing the oil therefrom, said tube having laterally-projecting supporting means ex tending longitudinally at the top thereof enaging undrnehth th top edges of'the stnp to opening throiighoiit the Iehgth of said or supportingand suspending said matel'ial tu e.
